[PATCH v2 0/2] acpi: battery: Query BCT method and steamdeck

From: Umang Jain

Date: Wed Sep 23 2026 - 04:28:27 EST


Short series to query Battery charge time ("_BCT") from ACPI tables
(1/2).

Patch 2/2 handles the case where steamdeck devices can report "Charging"
even when low power PSU is connected which is discharging the device.

Changes in v2:
- comment improvements
- split off BCT method handling into separate patch

v1:
